Study Notes
Shielded Metal Arc Welding (SMAW)
- Shielded Metal Arc Welding (SMAW) is commonly referred to as Stick welding.
Characteristics of SMAW
- A key characteristic of SMAW is the use of a flux coating on the electrode.
Function of Flux Coating
- The flux coating on the electrode in SMAW protects the arc and molten metal from the atmosphere.
Type of Current Used
- Direct Current (DC) is commonly used in SMAW, although some machines can also be used with Alternating Current (AC).
